PIFA antenna design for 4G wireless communications

摘要

The frequency bands that should be supported by mobile devices have increased significantly by the advent of the fourth generation (4G) of cellular communications. Therefore, the design of RF transmitter/receiver modules (including antennas) of the mobile devices should take this requirement in consideration. In this paper we discuss the effect of Planar Inverted F-Antenna (PIFA) dimensions on its resonance frequency, and the frequency bands supported by PIFA. Consequently, we come up with an empirical equation that describes this relationship.
